TELEPHONE INSTRUMENT.

Specification of Letters Patent.

Patented Nov. 14, 1905.

Application filed August 19, 1904:. Serial No. 221,384.

To all whom it may concern Be it known that I, EGBERT A. REYNOLDS, acitizen of the United States of America, and a resident of the city,county, and State of New York, have invented certain new and usefulImprovements in Telephone Instruments, of which the following is aspecification, reference being had to the accompanying drawings, forminga part thereof.

My invention relates to improvements in telephone instruments, andparticularly in cases or boxes therefor.

My invention consists in an improved form of box or case adapted tocontain all the apparatus necessary for a complete coin-controlledparty-line telephoneinstrument. Specifically I provide a metallic casehaving fixed back, sides, and bottom, and hinged front and top, saidcase having a removable diaphragm so located as to divide the interiorvalve into two parts and arranged as a complete support for theringercoils, the privacy device, the telephone hook and switch, theinduction-coil, and other elements of the instrument, said diaphragmarranged to slide in a suitable guideway, so that it may be readilyremoved by the mere opening of the hinged portion of the case and uponremoval to carry with it all the said elements, whereby they may bereadily removed or replaced, or whereby, if it should be desired, anentire new telephone set may be replaced for the old set withoutremoving or changing the box or case in any manner.

To these ends my invention consists in certain novel detailsofconstruction and combination of parts, as will be hereinafter fully setforth.

I will now proceed to describe an instrument embodying my invention andwill then point out the novel features in claims.

In the drawings, Figure 1 is a view in front elevation of a telephoneinstrument embodying my invention, certain portions of the same beingbroken away in order to illustrate other portions. Fig. 2 is a View,partly in side elevation and partly in central transverse sectiontherethrough, with certain portions removed. Fig. 3 is a view in centralvertical section through the instrument, showing the diaphragm and partssupported thereby in position in the casing. Fig. 4 is a view of thediaphragm and parts supported thereby removed from the casing. Fig. 5 isa top view of the instrument. Fig. 6 is a detail view of a money-safeemployed removed from the instrument.

The instrument shown herein comprises a casing having a fixed bottom 1,sides 2, and back 3. The front and top 5 are secured together and arehinged at 6 to the bottom'l. In Fig. 2 the front and top, constitutingthe door of the machine, are shown as partially open. In Fig. 1 the sameis closed. A suitable lock 7 may be provided by which the front 4 andtop 5 may be securely locked in position with respect to the mainportion of the casing. The transmitter 8 is carried by the front 4,being suitably connected thereto, as by a hinged or pivoted connection9, in a manner as will be readily understood by reference tothe'drawings. the lower left-hand side of the casing, resting upon thebottom 1. The front 6f the moneysafe is fitted to a cut-away portion inone of the sides 2 of the casing, forming when in position acontinuation of the said Side 2. The upper edge of the front of themoneysafe is provided with a projection 11, which fits a correspondingrecess 12 in the side 2 of the casing, whereby the safe will beprevented from being removed through the front of the instrument whenthe front door is open. The

A money-safe 10 is located in money-safe comprises the front 13, beforereferred to, a bottom 14, a rear wall 15, and sides 16, all securedtogether. A top or cover 17 is loosely fitted thereto, the rear end ofthe cover 17 being provided with lugs 18, arranged to enter recesses 19in the upper end of the rear wall 15 of the safe. When the safe is inpositiomthe front edge of the top 17 is retained in position by anabutment20 in the side wall 2 of the casing, while the lugs 18 at therear thereof hold such part of the top 17 from movement, whereby thesaid top 17 can only be removed after the safe as a whole has beenwithdrawn from its position in the casing. The top 17 has a coin-slot21, through which it will receive coins from the apparatus in the casingduring the operation of the machine. A lock 22, carried by the front 13of the money-safe, is arranged to engage the side wall 2 of the casingto retain the money-safe in position during the normal operation of themachine. By the foregoing it will be seen that the money-safe may bewithdrawn without opening thefront of the machine, while opening of thefront of the machine will in no has an opening 24: for the reception ofcoins,

another opening 25 for the reception of an electric push-button forminga part of the interior mechanism, and an opening 26 for the reception ofa busy-signal 27. The side walls 2 of the casing are each provided witha slideway 28, arranged for the reception of a diaphragm or slide 29.The diaphragm or slide may be freely inserted in place through the opentop of the machine along the guideways 28 and as freely removedtherefrom. This diaphragm 29 is arranged to carry all the working partsof the telephone,which include ringer-coils 30, privacy device 31,telephonehook 32, busy-signal 27, coin-chute 4:1, induction-coil 33, &c.The bells s4 belonging to the ringing device are secured to the bottom 1of the casing; but the clapper 35 is mounted upon the diaphragm 29, asare the coils operating'same, VVhe'n now it becomes necessary to obtainaccess to the various parts in the instrument for the purposes ofrepair, adjustment, or replacement, it is only necessary to unlock thetop and front 4 and 5 by manipulation of the lock 7, when the front andtop maybe swung down out of the way, en-

.tirely exposing the parts carried by thediaphragm 29. In order now toobtain more complete access to these parts, the diaphragm may be liftedbodily out of place, carrying with it all the various elements going tomake up the complete telephone instrument. if the damage is tooextensive to be readily repaired, an entire new set may be replaced forthe set removed and may be immediately inserted without any change,repairs, or alterations being necessary to the casing.

In order to add to the rigidity of the structure, I have employed abrace-rod 38, which extends from and-between the two sides 2 2, wherebythey are held securely together against any tendency to spring apart.One of the sides 2 is provided with an opening 37, through whichreturn-coins may be removed, and a return-coin chute 38 is alsoprovided, such return-coin chutes being sprung into place after thediaphragm 29 has been insert- @QQASE ed and retained in such place bymeans of a projection 39 thereon, which is arranged to enter an orificeor recess 40 in the diaphragm or a part carried thereby. It will henoted that the various parts carried by the diaphragm 29 are allarranged on the frontface thereof, so that they are contained within'thefront one of the two chambers into which the casing is divided by thediaphragm. The rear chamber may be occupied by the condenser, usuallyemployed in the ringing-circuit of this type of instrument.

It will be seen that by my invention lhave provided a compact form of.box or casein which all the elements necessary for a complete party-linecoin-controlled telephone in strument may be received and that l haveprovided means whereby all the working parts may be very readilyremoved.

What I claim is 1. In a telephone instrument, the com bination with abox or casing comprising a fixed back, bottom, and sides, and a coverconstituting the front and top portions, hinged to the fixed portion,the sides having oppositelyarranged vertical guideways open cnded intothe top portion of the opening closed by the hinged portion, and adiaphragm fitted to slide in said guideways, and removable through saidopening, said diaphragm dividing the casing into two compartments, oftelephone elements supported by said diaphragm.

2. In a telephone instrument, the combination with a box or casingcomprising a fixed back, bottom and sides, a top and front portionsecured together and hinged to themain fixed portion, and a removablediaphragm fitted to the main fixed portion dividing the easing into twocompartments, of telephone elements, including a telephone-hook,induction-coil, ringer-coils and a clapper supported by said diaphragmand removable therewith, bells secured to the main portion of saidcasing at the exterior thereof, and a transmitter secured to the hingedportion of the said casing, substantially as set forth.

In witness whereof I have hereunto set my hand this'l5th day of August,1904.
